A mini-keg is a small, portable container designed to hold and dispense beverages, typically beer. These kegs usually have a capacity of 5 liters, making them ideal for personal use or small gatherings. They are often made of stainless steel or aluminum, which helps maintain the beverage's freshness and carbonation. Mini-kegs come equipped with a tap system, allowing users to pour drinks easily. They are popular among craft beer enthusiasts and can be found in various styles, including those from local breweries. Many mini-kegs are reusable, promoting sustainability and reducing waste in the beverage industry.
